Overview

Dallas, perched in the northern reaches of Texas, is a global business hub and the ninth‑most populous city in the United States, home to roughly 1.3 million residents as recorded in the 2020 census. Spanning nearly 386 square miles (1,000 km²), the city’s footprint stretches into Collin, Denton, Kaufman, and Rockwall counties, making it a geographic and administrative centerpiece of the Dallas–Fort Worth metroplex. This metroplex, with an estimated 8.5 million people, ranks as the fourth‑largest metropolitan area in the nation and the most populous in Texas, anchoring the largest inland metropolitan region in the U.S. that lacks a navigable waterway to the sea.

The city’s skyline—dominated by the Reunion Tower, the Bank of America Plaza, and a growing cluster of modern high‑rises—mirrors its economic breadth, which spans finance, technology, telecommunications, transportation, and the arts. Dallas is also a cultural crossroads, boasting world‑class museums such as the Dallas Museum of Art, the Nasher Sculpture Center, and the Perot Museum of Nature and Science, alongside a vibrant music scene that ranges from country roots to contemporary indie beats. Its culinary landscape reflects the city’s multicultural makeup, offering everything from classic Texas barbecue to authentic Mexican, Vietnamese, and Ethiopian fare.

History/Background

Dallas traces its origins to 1841, when a small settlement known as “Dallas Town” was founded by John Neely Bryan near the Trinity River. The city was officially incorporated in 1856, taking its name from George Mifflin Dallas, the 11th Vice President of the United States. The arrival of the Houston and Texas Central Railway in 1872 transformed Dallas into a pivotal rail hub, spurring rapid population growth and establishing it as a commercial gateway to the West.

The early 20th century saw Dallas diversify beyond cotton and livestock into oil, banking, and manufacturing. The Dallas Market Center, opened in 1957, cemented the city’s reputation as a wholesale trade powerhouse. The tragic Assassination of President John F. Kennedy in 1963, occurring at Dealey Plaza, thrust Dallas onto the global stage and prompted a period of introspection and civic renewal. In the latter half of the century, the city embraced suburban expansion, high‑tech industries, and a burgeoning arts district, culminating in the Dallas Arts District, the largest contiguous urban arts district in the United States.
